This inve'ntion relates to a safety razor construction and it aims to provide a novel form having a magazine containing the safety razor blades which are through the instrumentality of 5' novel means, adapted to beejected when. dull,

- on the line l-l' of Figure 3;

anda new blade substituted, without manual en-I gagement with the blade.

It is additionally aimed to provide a novel construction wherein the blade being. substituted, is

caused to move against and eject the used blade without danger of contact of its cutting edge with the used blade.

It is further'aimedto provide novel means for holding a blade in operative position in combination with a slide, the latter being movable for blade ejecting and blade feeding operations.

The more specic objects and advantages will become apparent from a consideration of the description following taken in connection with f accompanying drawings illustrating an operative embodiment.

In said drawings:-- Figure l is -a View in -side elevation of the improved razor construction or holder, the same partly being in section to disclose details;

Referring specifically to the drawings, the holder has a. magazine at I3 in which a pluralityof razor blades Ill are verticalli7 disposed orstacked as best shown in Figures 3, 5, and 7. .Extending centrally from the rear side of themagazine is a, tubular handle lclosed at its free end prefer- 2S are provided, being disposedin the hood 29a ably by afscrew plug I6. Within the handle l5 is a ,compressed coil spring lll bearing against a head i8 of a plunger rod I9 slidably mounted in .a bearing 2i). such bearing serving as a coupling to connect the magazine and handle, such `parts being telescopedv over the coupling `or bearing 2G by means of screws or other fastenings- '2| being detachably connected thereto.

At the forward end,' the rod I9 carries a follower 22 which bears against the stack of razor blades Hi and urges them forwardly. Integral with vthe magazine and depending from the lower forward edge thereof is a` guard plate 23 vtoothed at its lower edge as at 2@ 'and against which vguard plate the blades lll, one at l5 a time, are operatively positioned. Said blades are sharpened at their lower edges 25 preferably on a single bevelV and from. one side thereof as shown, corresponding with thebevel of all of the lower edges 'of the parts of the holder adjacent said blade as best shown in Figures 3 and 5.

vertically slidable in the holder, forwardly of the magazine, is a holding and ejecting plate 26.- Said plate 26 is positioned and guided between a front wall 2l 'of the magazine or holder and side .walls 28,-the structure being enlarged 'above the'rnagazine to provide a hood 29a intowhich the slide 26 extends when retracted. Said slide or plate 26 has slots 3U to receive lingers 29; said fingers 29 being part of a bell crank lever completed by a shaft 3l journaled in the side walls' of the hood, and exteriorly of the same having an arm 32ffixed thereto at bifurcated portions 33 of such arm. Preferably two of the lingersA and 'extending into the aforesaid lslot or slots 3i) ofthe slide plate '25. -Plate 26 isurged down; wardly since a leaf spring 3@ is disposed within `the hood fastened to or engaging the. upper wall thereof, and also serving to urge plate 26 by urging fingers 29. Y y In the lowered position of the plunger or plate v26,- when the blade Hl is in operative-position as in'Figure 3, a shoulder 35 on the plate 26, engages the -upper edge thereof and two of 'four spring or resilient lugs 3S on the plate' 26 clip into a pair of notches 3l in the upper vedge of th'e blade lll, lugs 38 being provided at the outer extremities of the upper edges, for direct engagerrient with said shoulder 35. l

The blade is held inthe operative position, as shown in Figure 3 partly by means of the pair of lugs 36 disposed in the notches 3T, and is also held in 'operative position through -the engagement of a pair of rollers 40, rigid or journaled on a rod 4I surrounded by rubber tubing 42, such parts being housed in a groove or slot 43 in the guard 23, and being urged outwardly by a blade spring 44, said rollers or projections 40 being adapted to enter, under urgency of the spring 44, slots45 provided through the bladeA at opposite ends thereof. The frictional action of the rubber 42 and its abutment with the blade I4 aids in maintaining the blade I4 operatively positioned. 'I'he rod 4I, sleeve 42 and rollers 40 willreadily yield against tension of the spring 44 when a blade I4 is ejected by downward movement.

When the blade I4 in operative position, as in Figure 3, is dull and is to be discarded, arm 32 is moved upwardly and rearwardlysto its limit, thus raising the plate 26 above the magazine or until its shoulders are above the lugs 38 of the blade in the magazine, whereupon through expansion.

of spring I1, the foremost blade in the magazine, is moved forwardly out of the magazine and beneath the shoulder 35. Thereupon the arm 32 is moved to its normal position, partial movement being suggested in Figure 5, the blade I4 which is uppermost being urged by the plate 26, and by moving into contact with the lower blade I4 displaces the lower blade I 4, and takes its place.

Attention is called to the fact that the lugs 38 of the blade in operative position are engaged by notched corners 46 of the blades above them, holding the cutting edge of the upper blade,

spaced above the main portion of they upper edge of the lower blade, as suggested in Figure 12, to prevent nicking or marring of such cutting edge.

Attention is also directed to the fact that the positions of the openings 31 of alternate blades in the stack of blades within the magazine, are different. Because of this fact, the pair of resilient fingers 36 engaging the notches 31 of a blade cannot project inwardly pastv such notches and engage notches of the following blade, overcoming any possibility of the engagement and accidental feeding of two blades at a time. It will be obvious that after one pair of fingers 36 engage one pair of slots 31, the other pair of fingers 36 will engage the pair of slots 31 of the next blade, which are differently positioned as stated.

The razor is used or handled in the usual or obvious manner.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:-
